Electronic war on the jelly fish

Cala Sant Vicenç, one of the beaches to have been closed this summer because of an invasion of jelly fish could be one of the areas for a pilot scheme to combat the plagues of jelly fish which move into Balearic waters every summer. The pioneering plan involves the strategic placing of electronic buoys in the water which give out high frequency ultrasonic signals which will kill venomous cells in the jelly fish's tentacles, causing them to literally drop off from the body. Beaches all over Majorca were affected by the jelly fish invasion at the start of the summer and a long list of beaches were closed while a clean up operation was mounted. However Red Cross stations on the beaches are still having to treat jelly fish stings on a near daily basis. The authorities, if successfull and effective, are expected to use the electronic buoys at all of the island's key beaches.
